Image forming apparatus

Abstract

An image forming apparatus includes a housing, an discharge tray, a discharging roller pair, a main board, a wireless communication unit including a first wireless communication board. The housing includes a first part and a second part. The first part is arranged at a downstream side of a nip of the discharging roller pair, and an upper surface of a side wall of the first part is arranged at a lower position with respect to the nip. In the second part, the discharging roller pair is positioned. The second part is arranged at an upstream side of the first part. An upper surface of a side wall of the second part is arranged at a higher poison with respect to first part. At least part of the wireless communication unit is arranged at a higher poison with respect to the side wall of the first part.

What is claimed is: 
     
       1. An image forming apparatus, comprising:
 a discharge tray; 
 a housing having an upper surface at which the discharge tray is provided, the housing including: 
 a top cover arranged at a higher position with respect to the discharge tray; 
 a first side cover arranged at one end part of the housing; and 
 a second side cover arranged at another end part of the housing; 
 a discharging roller pair configured to discharge a sheet, in a discharge direction that is directed from the second side cover toward the first side cover, to the discharge tray, a nip point of the discharging roller pair being arranged at a higher position with respect to a lowest end of the discharge tray; 
 a main board arranged in the housing; and 
 a first wireless communication board being connected to the main board, the first wireless communication board being arranged between the second side cover and the discharging roller pair in the discharge direction, the first wireless communication board being arranged under the top cover and between the lowest end of the discharge tray and the nip point of the discharging roller pair in an upper-lower direction, at least a part of the first wireless communication board being arranged at a higher position with respect to the main board. 
 
     
     
       2. The image forming apparatus according to  claim 1 ,
 wherein, when viewed from a side of the image forming apparatus, the at least a part of the first wireless communication board overlaps a discharge path space guiding the sheet to the discharging roller pair. 
 
     
     
       3. The image forming apparatus according to  claim 1 , wherein the first wireless communication board is arranged at a position which does not overlap the discharging roller pair when viewed from the side of the image forming apparatus. 
     
     
       4. The image forming apparatus according to  claim 1 ,
 wherein the main board is arranged under the top cover and the discharge tray. 
 
     
     
       5. The image forming apparatus according to  claim 1 ,
 wherein a switchback path used to switch front and rear of the sheet is formed under the top cover, at least a part of the switchback path being arranged at a higher position with respect to the discharging roller pair. 
 
     
     
       6. The image forming apparatus according to  claim 1 ,
 wherein the first wireless communication board is directly connected to the main board. 
 
     
     
       7. The image forming apparatus according to  claim 1 , further comprising:
 a second wireless communication board provided separately from the first wireless communication board; and 
 an operation panel unit arranged between the first wireless communication board and the second wireless communication board. 
 
     
     
       8. The image forming apparatus according to  claim 6 , wherein at least a part of the operation panel unit protrudes, in a width direction perpendicular to the discharge direction, from a side wall of the housing. 
     
     
       9. The image forming apparatus according to  claim 1 ,
 wherein the top cover is arranged at a nearer position to the second side cover with respect to the discharge tray in the discharge direction. 
 
     
     
       10. The image forming apparatus according to  claim 1 ,
 wherein the housing has a side wall, the side wall having an openable cover configured to open and close an opening formed on the side wall, and 
 wherein the first wireless communication board is configured to be attached to and detached from the main board through the opening when the openable cover is open. 
 
     
     
       11. The image forming apparatus according to  claim 1 ,
 wherein the top cover being arranged at a nearer position to the second side cover with respect to the discharge tray in the discharge direction, and 
 wherein the first wireless communication board is a board for a wireless LAN communication.
